ctroller lets you use your 3DS as an input device for your Linux system via
the uinput kernel module. It consists of a client that runs on your 3DS,
continously streaming the 3DS input data to a server on your PC. The server
exposes a virtual device to your system, interpretes the data it receives and
writes it to a event node under
/dev/input/event* or similar.
To run the server, the
uinput kernel module needs to be loaded:
$ modprobe uinput
make to build both components, or enter either of the
subdirectories to build them individually by running
make there. You can use
debug target for development.
Install the server to your system by running
make install. This is equivalent to:
$ cd linux $ make install DESTDIR="" BINDIR="/usr/bin"
You can set
DESTDIRto a install to a different location, i.e.
make DESTDIR="/my/fakeroot/environment"installs ctroller in
Download the latest release of the 3DS binaries.
Or you can build them yourself:
$ cd 3DS $ make release
ctroller.ciawith the CIA-manager of your choice.
If you want to install the 3DSX-executable:
/3ds/ctroller/on your SD card. You can also directly upload the application to your 3DS using upload.sh (do not blindly execute unknown scrips, I'm not responsible if this accidentally deletes your SD card or unfreezes your fridge). To do so, start a FTP server (such as ftpd) on your 3DS on port 5000, then run:
$ cd 3DS $ make upload DSIP=<IP of your 3DS here>
ftpto be installed on your system.
Create a directory
ctrollerin the root of your SD card
Place 3DS/ctroller.cfg in there and replace the IP with the one of your PC. (The config file should now be at
Start the server by running:
-d --daemonize execute in background -h --help print this help text -p --port=<num> listen on port 'num' (defaults to 15708) -u --uinput-device=<path> uinput character device (defaults to /dev/uinput)
Then launch the ctroller.3dsx application on your 3DS using a homebrew launcher of your choice.
For development purposes, the 3DS-Makefile includes a
run target that uses
3dslink to upload and run the application using the Homebrew Menu NetLoader.
This program is intended to be used in a private network. For simplicity, the server right now accepts any connection on it's port, which might pose a security risk if others can send data to it. This will be changed in future releases. For now, you probably shouldn't be using this in a public network.
